Following reports that some of the replacement Galaxy Note 7 units have been catching fire, Samsung has made changes to the new Note 7 production schedule. Samsung initially recalled the Galaxy Note 7 after a number of units caught fire, before conducting further tests and issuing replacements. However, it appears that the handset still may not be safe.

We reached out to Samsung regarding the matter and a spokesperson told us:

We are temporarily adjusting the Galaxy Note 7 production schedule in order to take further steps to ensure quality and safety matters.

While this isn’t a completely transparent message, an adjustment to the production schedule sounds a lot like a halt in Galaxy Note 7 shipments. Verizon, T-Mobile and AT&T have already stopped shipping replacement Galaxy Note 7s amid concerns regarding overheating.

Last month, major airlines told Galaxy Note 7 owners not to access the device while on board, but reports of a seemingly safe replacement unit ‘smoking’ on a US flight last week has reignited worries.
